Describe the bug
Villagers of the two tech reborn professions display the purple + black missing texture when converted to a zombie.

Steps to Reproduce

1. Place an unemployed villager next to either an alloy iron furnace or a generator.
2. When it has acquired a profession, let it be killed by a zombie (hard for 100% chance of conversion).
3. Look at the villager with the missing texture.

Screenshots

Environment:

• Minecraft: 1.19
• Mod Loader: fabric 0.14.6

I have this issue, but for me it sometimes also results in a crash. I am running a modpack I'm creating, and it throws a FileNotFoundException because it can't load techreborn:textures/entity/zombie_villager/profession/metallurgist.png

Simple fix.

In the meanwhile you can also make a datapack and copy tech reborn villager textures to assets/techreborn/textures/entity/zombie_villager/profession/
